A Robust Reputation Management Mechanism in the Federated Cloud
Abstract
In the cloud computing paradigm of the Infrastructure as a Service (IaaS), computational resources are available for rent. A Robust reputation management mechanism in the federated cloud Although it offers a cost-effective solution to virtual network requirements, low trust in the rented computational resources prevents users from using it. Computational resources are shared to reduce the cost, i.e. multi-tenancy exists.
Advantages
- In this paper we propose a RMM with a focus on multi-tenancy. Sharing computational resources with others is the main concern of users as other co-tenants may be malicious.
- In this paper, we propose a RMM that considers the CP’s capability and willingness to make such differentiation among its users.
- It allows maximum co-tenancy irrespective of the behaviours of the users
Disadvantages
- This mechanism is vulnerable where the service provider faces competition and may send unfair feedbacks about its competitors.
- This model assumes that seller agents act consistently, which might not be true in many cases.
System Configuration
Platform : cloud computing
Conclusion
Co-tenancy makes cloud computing affordable, but from malicious co-tenants it also introduces new risk. For the allocation of safe co-tenants, a user depends on the CP. Our aim in this paper is to develop an RMM that encourages CPs to make correct segmentation between good and malicious users, i.e. a good user only gets other good users as cotenants.
